Description

Technical Field

[0001] The invention relates to the field of vegetable grafting and cutting, in particular to a cutting device used for vegetable grafting. Background Art

[0002] Grafting is one of the artificial propagation methods of plants, which involves grafting the branches or buds of one plant onto the stem or root of another plant so that the two connected parts grow into a complete plant.

[0003] At present, most horticultural plants and most fruit and vegetable crops are grown by grafting seedling technology, but grafting operations are still mainly done manually, with skilled workers grafting at a speed of 120 to 150 plants per hour, which seriously affects the promotion and application of grafting seedling technology. There are the following problems with manual grafting: First, the grafting techniques and proficiency levels of grafting personnel are different, making it difficult to ensure the standardization of the production quality of grafted seedlings, thus affecting the survival rate of grafted seedlings. Second, manual grafting is time-consuming and labor-intensive, with low production efficiency, and the quality of the work will decrease as the operation time increases.

[0004] In the grafting process, the cutting quality of the scion and rootstock is the most critical and important link, which directly determines the survival rate and efficiency of the grafting. However, manual cutting is difficult to ensure the uniformity of the cut surface, the cutting speed is slow and the survival rate of the grafted seedlings is low.

[0005] However, most of the existing grafting and cutting devices are mechanical equipment driven by motors, which are large in size and cannot be carried into the vegetable seedling cultivation greenhouse to graft and cut the vegetable seedlings. If the vegetable seedlings are transported to the cutting device, it is time-consuming and laborious, and the extra time consumed will also affect the efficiency of grafting. Summary of the invention

[0006] In view of the problems in the prior art, the present invention provides a cutting device for vegetable grafting.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a cutting device for vegetable grafting, comprising two symmetrically arranged clamping frames and holding frames, each of the clamping frames is fixedly connected to the outer wall of the holding frame, and the side wall of the holding frame adjacent to the holding frame is fixedly connected to the hinge frame, and the two hinge frames are hinged by a first pin shaft;

[0008] A travel groove is provided inside the holding frame, a buckle frame is hinged inside the travel groove through a second pin shaft, the second pin shaft rotates and passes through the holding frame and the buckle frame in sequence, a groove is provided on the outer wall of the clamping frame, the groove is communicated with the travel groove, a push block is movably connected inside the groove, a cutter is fixedly connected to one side of the push block, a spring is fixedly connected to the other side of the push block, an outer shell is provided at the other end of the spring, the outer shell is connected to the outer wall of the clamping frame, and the end of the spring contacts the inner wall of the outer shell;

[0009] The cutter is arranged obliquely, and the top of the clamp frame and the top of the outer shell are respectively provided with a first cutting groove and a second cutting groove corresponding to the cutter, and the cutter is slidably connected with the inner walls of the first cutting groove and the second cutting groove.

[0010] Specifically, the first pin shaft rotates and penetrates through the two hinge frames, and a torsion spring is sleeved on the shaft wall of the first pin shaft located between the two hinge frames, and two ends of the torsion spring are respectively in contact with the two buckle frames.

[0011] Specifically, one end of the push block is fixedly connected to a limiting slide block, and a matching limiting slide groove is provided on the inner wall of the outer shell corresponding to the limiting slide block, and the limiting slide block is slidably connected inside the limiting slide groove.

[0012] Specifically, an adjusting bolt is threadedly inserted into one end of the outer shell away from the clamping frame, and one end of the adjusting bolt extends into the interior of the outer shell.

[0013] Specifically, an adapting groove is formed through the outer wall of the outer shell on the side close to the buckle frame, and the adapting groove is adapted to be arranged to fit the buckle frame.

[0014] Beneficial effects of the present invention:

[0015] The cutting device for vegetable grafting described in the present invention has a simple structure and is easy to use. By arranging a hinged buckle frame on the clamping frame and the holding frame, the holding frame will first rotate with the second pin shaft as the axis during the holding and buckling process to push the push block to drive the cutter to contract. When the clamping frame is clamped on the rhizome of the vegetable seedling, the cutter can be reset under the elastic force of the spring. The reset inclined state of the cutter can cut the rhizome of the vegetable seedling, and it can semi-automatically complete the cutting of vegetable grafts. In addition, the elasticity of the spring drives the cutter to perform cutting operations, which can ensure the uniformity and inclination of the cutting surface, improve the cutting efficiency and quality, and its small size can be conveniently carried to the inside of the vegetable seedling nursery greenhouse for grafting cutting, further improving the cutting efficiency.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 8 As shown, a cutting device for vegetable grafting according to the present invention comprises two symmetrically arranged clamping frames 1 and holding frames 2, the outer wall of each clamping frame 1 is fixedly connected to the holding frame 2, the side wall of the holding frame 2 adjacent to the side wall is fixedly connected to the hinge frame 3, and the two hinge frames 3 are hinged by a first pin 4;

[0028] A travel groove 6 is provided inside the holding frame 2, and a buckle frame 8 is hinged inside the travel groove 6 through a second pin shaft 7. The second pin shaft 7 rotates and passes through the holding frame 2 and the buckle frame 8 in sequence. A groove 9 is provided on the outer wall of the clamping frame 1, and the groove 9 is communicated with the travel groove 6. A push block 10 is movably connected inside the groove 9. A cutter 12 is fixedly connected to one side of the push block 10, and a spring 14 is fixedly connected to the other side of the push block 10. An outer shell 15 is provided at the other end of the spring 14. The outer shell 15 is connected to the outer wall of the clamping frame 1, and the end of the spring 14 contacts the inner wall of the outer shell 15.

[0029] The cutter 12 is arranged at an angle, and the top of the clamp frame 1 and the top of the outer shell 15 are respectively provided with a first cutting groove 13 and a second cutting groove 17 corresponding to the cutter 12 , and the cutter 12 is slidably connected to the inner walls of the first cutting groove 13 and the second cutting groove 17 .

[0030] The first pin shaft 4 rotates and passes through the two hinged frames 3, and the first pin shaft 4 is located on the shaft wall between the two hinged frames 3 and is sleeved with a torsion spring 5, and the two ends of the torsion spring 5 respectively contact with the two buckle frames 8. The elastic force of the torsion spring 5 can push the buckle frames 8 to shrink toward the inside of the travel groove 6 with the second pin shaft 7 as the axis, and when the buckle frames 8 contact the inner wall of the travel groove 6, it can drive the holding frame 2 to be in an open state and make the clamping frame 1 in a closed state.

[0031] One end of the push block 10 is fixedly connected to the limit slider 11, and a corresponding limit slot 18 is provided on the inner wall of the outer shell 15 corresponding to the limit slider 11. The limit slider 11 is slidably connected inside the limit slot 18. When the limit slider 11 slides inside the limit slot 18, the push block 10 can be effectively made more stable when moving.

[0032] An adjusting bolt 19 is threadedly inserted into one end of the outer shell 15 away from the clamping frame 1 , and one end of the adjusting bolt 19 extends into the interior of the outer shell 15 . The setting of the adjusting bolt 19 can effectively limit the moving length of the push block 10 .

[0033] An adaption groove 16 is formed through the outer wall of the outer shell 15 on the side close to the buckle frame 8 , and the adaption groove 16 is adapted to the buckle frame 8 , which can effectively prevent the outer shell 15 from limiting the travel of the buckle frame 8 .

[0034] Specifically, in the initial state, that is, when being carried, the edges of the two cutters 12 overlap, which can effectively prevent the device from being accidentally cut by the edges of the cutters 12 during the carrying process, making the device safer to carry and store, and its small size can be conveniently carried to the inside of the vegetable seedling nursery greenhouse for grafting and cutting. Compared with large-scale mechanized cutting devices, it does not need to transport the vegetable seedlings, which saves a lot of time and manpower, and improves the cutting efficiency;

[0035] When in use, the device can be held in one hand, with the index finger and thumb located on both sides of the buckle frame 8 respectively. When the two fingers exert force to press the buckle frame 8 in adjacent directions, the buckle frame 8 will overcome the elastic force of the torsion spring 5 and close together, and the buckle frame 8 will rotate with the second pin shaft 7 as the axis. The end of the buckle frame 8 can push the push block 10 inside the outer shell 15 to move away from the clamping frame 1 when flipping. The push block 10 can drive the cutter 12 to shrink from the inside of the first cutting groove 13 to the second cutting groove 17 on the outer shell 15 when moving. When the two fingers continue to exert force, the buckle frame 8 is as attached Figure 4 In the state shown, the outer wall of the buckle frame 8 overlaps with the outer wall of the holding frame 2, and the outer wall of the push block 10 contacts the adjusting bolt 19, so that the buckle frame 8 cannot continue to turn outward with the second pin shaft 7 as the axis. At this time, the two fingers will contact the holding frame 2. With the continuous pressing of the two fingers, the holding frame 2 will drive the clamping frame 1 to be in an open state with the first pin shaft 4 as the axis. At this time, the clamping frame 1 is as shown in the attached Figure 3 In the state shown, the clamping frame 1 can be aligned with the rhizomes of the vegetable seedlings to be grafted and cut, and the pressure on the holding frame 2 and the buckle frame 8 can be released. At this time, the holding frame 2 and the buckle frame 8 will be reset under the elastic force of the torsion spring 5. After the buckle frame 8 is reset, the push block 10 loses its restriction and is reset under the elastic force of the spring 14. The push block 10 can cut the vegetable seedlings located inside the clamping frame 1 while driving the cutter 12 to slide toward the first cutting groove 13 inside the clamping frame 1. After the cutting is completed, two fingers are used again to press the buckle frame 8 in an adjacent direction. Similarly, the clamping frame 1 can be opened and separated from the vegetable seedlings. Compared with pure manual handheld cutting with a cutter, its semi-automatic cutting method can effectively ensure the uniformity and inclination of the cutting surface and the cutting efficiency. Novices can also perform cutting operations, and it is small in size and easy to carry.
